How is Behcet Syndrome diagnosed?

No specific test will confirm BD. Doctors have to look at your overall health and various symptoms because they don't happen all st the same time usually. Rheumatologist, Dermatologist, General Practioner, Opthamologist

My diagnosis was made by an Opthamologist and later confirmed by 3 different Rheumatologists. Generally a Rheumatologist would be the preferred specialist for someone diagnosed with Behcets; however, patients should also be followed by specialists who can assess and treat specific symptoms that the patient has. For example I see an opthamologist on a regular basis to ensure my eyes do not have any inflammation. There is a skin test that you can take to confirm Behcets; however, not all individuals with Behcets test positive for this test. The diagnosis is usually made based on an assessment of the patients symptoms.

There is no definitive test for BD. Skin markers test is the most reliable at this time. A rheumatologist generally makes the final diagnosis. There are inflammatory blood tests that can be performed yet many come back normal. MRIs of the brain can also be performed to check for neurological involvement. Genetic information can also be useful.

There is no specific test it may come down to your symptoms and possibly a pathergy test

There is a list of various symptômes. A dermatologist, an eye doctor, a rheumatologist, a GI Dr, a neurologist, an OB-gyn can diagnose Behcet. Also a blood test can be done : HLA-B51 positive is a sign.

Therr is no 1 straight forward test

Recurrent genital ulcerations
Eye lesions (uveitis or retinal vasculitis) observed by an opthalmologist
Skin lesions (erythema nodosum, pseudofolliculitis, papulopustular lesions, acneiform nodules) found in adult patients not being treated with corticosteroids
Positive "pathergy test" read by a physician within 24-48 hours of testing
ANA test

There is no cut and dry test to tell you have Behcet's. It is really diagnosing by symptoms, watching blood tests for inflammation, and the symptoms that present themselves. A doctor has to watch the symptoms and see what developed.

I think Behcet's is diagnosed by symptoms and previous diagnosis with other criteria such as oral, genital ulcers, uveitis and eye problems, rashes, particular arthritis type symptoms, fatigue. There is a pathergy test to see if you have a certain reaction to a needle poke. Then a lot of patients are positive for HLA- b51 or 52.

It is a clinical diagnosis which means there is NOT a test. There are international standards with a point system. Everyone must have oral apthous ulcers. It is the hallmark of the disease we all share. If you break out three times or more a year, you get the first point. It's best to be evaluated by a Dermatologist who specializes in rheumatology and have a punch biopsy done. Don't worry, it isn't too painful and heals quickly. Then, you need to have two or more of the following in order to be diagnosed:
1) Recurrent genital ulcerations - we are usually misdiagnosed with HSV despite a negative test
2) Eye lesions (uveitis or retinal vasculitis) observed by an opthalmologist which is the leading cause of blindness in Japan, so don't mess around. You should keep eye drops on hand.
3) Skin lesions (erythema nodosum, pseudofolliculitis, papulopustular lesions, acneiform nodules) found in adult patients not being treated with corticosteroids that usually present on the arms or legs. They can be extremely painful. They usually look like a dry version of the ulcers in our mouths.
4) Positive "pathergy test" read by a physician within 24-48 hours of testing which is why we have false positives for TB tests.

I have had all five, but currently have three. I have been in remission and only had one.
